Reduced "staff" ailine tickets

Offered cheap airline tickets , supposedly unused staff tickets. We had to be available to fly to Johannesburg as soon as we were sent the ticket. We would only be given 24 hours notice. The man appeared to be a retired SAA employee. On one occassion in August he actually phoned and said he was trying for that week, so to be prepared. Needless to say nothing ever materialised.Scammed !
